摘要

提出了一种适用于混合天线系统的低频平面扼流交叉偶极子天线。该天线结构由传统的双极化交叉偶极子天线演变而来，但在辐射臂上增加了扼流圈元件。所提出的扼流圈结构能够减轻低频天线对高频天线的辐射阻断效应。初步结果表明，所提出的覆盖4G 2.19 GHz~2.54 GHz频段的低频天线对工作在3.25 GHz~3.61 GHz频段的5G高频天线影响较小，且辐射方向图一致性好，隔离度优于20 dB。

Planar Choked Cross-Dipole Antenna for Hybrid Antenna System Application

In this paper, a low-frequency planar choked cross-dipole antenna for hybrid antenna system application is proposed. The antenna structure is evolved from a traditional dual-polarized cross-dipole but consists choke elements on the radiating arms. The proposed choke structure is able to alleviate the radiation-block effect of the low-frequency antenna on the high-frequency antenna. Preliminary results show that the proposed low-frequency antenna covering the 4G band of 2.19 GHz~2.54 GHz has less effect and good consistency of radiation patterns on the 5G high-frequency antenna, which is operating in 3.25 GHz~3.61 GHz with isolation better than 20 dB.
